Good luck man! I will be smoke free for one year on the 21st of this month. I started when I was about 12 and stopped when I hit 44. Things to help you quit:
1. gum helped me
2. cold turkey...just do it
3. remember how nasty these things tasted on the very first pack you had? Yep, nasty.
4. these things cause more stress then resolve
5. You smell better, your house smells better, your car smells better, your clothing smells better
6. you will feel better.
